Synthesis, Structure and Properties of a New Iron (Ⅱ) Diphosphonate:[ NH3 (CH2)5NH3 ] [ Fe2 {O3PC (CH3) (OH) (PO3H) }2 ] · 2H2O(English) |

Abstract: | Under hydrothermal conditions, a new iron (Ⅱ) diphosphonate namely [ NH3 (CH2) 5NH3 ] [ Fe2 Ⅱ {O3PC (CH3)(OH) (PO3H) } 2] · 2H2O was synthesized and structurally characterized. The compound contains covalent doublechains of [ Fe2 Ⅱ { O3PC (CH3) (OH) PO3H } 2 ] n2n-, charge balanced by the protonated pentamethylenediamine. Thedouble chains are held together by very strong hydrogen bonds, forming a three-dimensional open network. Weakferromagnetic coupling is observed for the compound. |
